Initially, they set up basic States: `OrderReceived,` `PaymentVerified,` `ItemsPacked,` and `Shipped.` However, they have noticed a significant increase in customer inquiries about Order status, especially when Orders are delayed due to supplier issues. They want to add a new State called `SupplierDelay` to ensure that when an Order is in this State, customers receive a notification and the support team is alerted.
